Hello, my question is as follows:
1. At present, we have encountered a problem when debugging the board made by ls1012a chip. Now it is suspected that the frequency doubling of Platform PLL in the system has not been successful, is there have any way to measure the output of Platform PLL?
2. We found that the chip has a CLK_OUT pin, which only defines SYSCLK from the register definition in the manual. But we also see such a description of CLK_OUT "The CLK_OUT signal can be configured to offer one of a variety of internal clock signals to external hardware for debug or diagnostic purposes". Can this pin be configured to output platform PLL clock? If yes, how do I configure it?
